DETACHABLE SAW-HANDLE.

To all whom, it may concern.-

Be it known F RAZEE, a citizen of the United States, residing atPortland, in the county of Multnomah and State of Oregon, have inventednew and useful Improvements in Detachable Saw- Handles, of which thefollowing is a specification.

This invention has for its object to provide a convenient,readily-attachable, and ineX- pensively-made handle for saws, such asthe crosscut type, and also to embody therein means by which therelative position of the handle with respect to the saw-blade may bevaried from the vertical to the horizontal, as

found convenient.

My invention further has for its object to arrange the attachment of thewooden handgrip piece to the shank of the handle in such wise that theouter surface shall present neither elevation nor depression, butinstead shall be a continuoussmooth surface comfortable for the hand ofthe operator, and at the same time to prevent the handle shifting up ordown out of place in service.

To attain these objects, my invention comprises the features shown inthe illustrations of the drawings constituting a part of thespecification and representing as follows:

Figure 1 is a side elevation of my improved handle, showing the sameattached to a sawblade, as in practice, in one of its two positions.Fig. 2 is a section taken transversely of the saw on line indicated by 22 in Fig. 1 and looking in the direction indicated by arrows. Fig. 3 isa horizontal section on line 3 3 of Fig. 1 looking downward as indicatedby arrows. Fig. 4 is a partial view of the hand-grip piece and the shankto which the same is attached, the bearing-head 32 and nut 33, removablymounted on the shank, be ing omitted; and Fig. 5 is a transversesection, on a larger scale, on line 5 5 of Fig. 4 lookingforward.

My invention consists of a shank 22, which is a casting made with aT-shaped socket portion 22 comprising two malleable members 22 The shankis further made with a threaded portion 23, which is substantiallysquare in cross-section for the reasons below stated, and a projectingintegral member or tang 24 about one-fourth, in cross-section, the sizeof the shank and positioned in one corner thereof, as shown in Fig. 2.The tang that I, OAssrUs FREMONT.

24 is made with two straight faces disposed at right angles to eachother and provided with projecting lugs 25 26, made with locking-heads34, respectively.

The wooden hand-grip piece 21 is made with a peripheral recess a littlebelow the middle, and around such recessed part the members 22 are bent,so as to tightly grip the piece 21.

The parts are so constructed that when the hand-grip piece has beenfixed in the socket of the shank as described the exterior surfaces ofboth will be in unbroken alinement that is, present acontinuous evensurface-so as to afford a convenient grip to the sawyer. The same mannerof aHiXing the hand-grip piece to the shank also prevents the formerworking up out of its socket while using the saw.

On the threaded portion 23 of the shank is mounted a movablebearing-head 32 and a winged jam-nut 33. The bearing-head 32 is madewith projecting members 35 35 and a square opening by which it isadapted to be slipped off and on the square threaded portion 23 of theshank to change the position of the grip-piece of the handle withrespect to the saw-blade, as may be convenient to the work in hand, andthe bearing-faces of the members 35 have grooves extending lengthwisethereof, adapted to fit over and engage with the end edge of thesawblade.

In attaching my handle to the saw-blade so as to be in line therewiththe stud 25 is inserted through one of the holes 36 usually provided inthe saw-blade end, and the winged nut is then screwed up so as to causethe bearing-head 32 to engage with the saw end, as shown in Figs. 1 and3, in doing which the blade is moved forward and becomes engaged withthe locking-head 34 of the stud 25, by which it is rigidly held to thevertical inner face of the tang 24.

The square construction in cross-section of the part 23 of the shank andthe conforming shape of the opening in the bearing-head 32 are providedto hold the latter against turning on the shank, and by so doingpreventing the same from imposing any torsional strain dle from being inline with the saw-blade to a position at right angles with the same,- asindicated in dotted outline in Fig. 2, it is but necessary to loosen thenut 33, so as to be able to disengage the saw-blade from the stud 25 ofthe tang 24:, and the saw-blade may then be turned at right angles andengaged with the stud 26 on the other face of the tang. The bearing-head32 would also have to be turned at right angles on the shank of thehandle and the parts then locked by tightenin the nut 33, as in thefirst place.

l claim 1. In a saw-handle, shank made with a threaded head having Isquared sides, a tang as 24, projecting from one corner of such head,and made with two faces, disposed at right angles to each other andprovided with locking-studs 25, 26, respectively, arranged to interlockwith the end of a saw-blade, a movable bearing-head,

blade end, and made with an opening which fits said squared portion ofthe shank, and a adapted to engage with the edge of the sawthecombination of a jam-nut to force the bearing-head against the saw end.

2. In a saw-handle, the combination of a shank made with a threaded headhaving right-angular, cut-away side faces, a tang as 24, projecting fromone corner of such head, and made with two faces disposed at rightangles to each other and provided with locking-studs 25, 26,respectively, arranged to interlock with the end of a saw-blade; amovable bearing-head adapted to engage with the edge of the saw-bladeend, and made with an opening adapting such bearing-head to be placed onsaid shank-head in either one of the two positions at right angles toeach other; and a jam-nut to force the bearing-head against the saw end.

In testimony whereof I have hereunto affixed my signature in thepresence of two witnesses.
